have/has的句型转换

1.否定句

主语+don't (doesn't)+have +….例：

We don't have any water here.我们这儿没有水.

This wall doesn't have a window in it.这面墙上没有一个窗户.

2.一般疑问句：

Do (Does)+主语+have+…?

肯定回答：Yes,主语+do (does).

否定回答：No,主语+don't (doesn't).例：

—Do you have a ruler?你有尺子吗?

—Yes,I do ./No,I don't.是的,我有./不,我没有.

—Does Lucy have a twin sister?露茜有个孪生姐姐吗?

—Yes,she does./No,she doesn't.是的,有./不,没有.

注意：do,does是助动词,do用于第一、二人称单、复数和第三人称复数；does用于第三人称单数形式.回答一般疑问句时,主语用人称代词表示；否定回答中don't或doesn't 一般不分开写.

注意：have (has)表示“有”时,一般不用于进行时态.

另外,在现代英语中,当“有”讲时,have/has的一般疑问句可以把have/has直接提前,当have/has作助词时表示完成时态时也可以直接提前.例：

They have a book.Have they a book?

3.“have”与“there be句型”的区别

have意为“有”,指所属关系；there be表示“某地有某物”,意指“存在”.例：

There's a book on the desk.桌子上有本书.

Xiao Wang has an English-Chinese dictionary.小王有本英汉字典.
